A truck driver charged in a weekend crash that killed a man and injured comedian Tracy Morgan and others in New Jersey was awake for more than 24 consecutive hours before the incident, a criminal complaint filed in the case says.

Kevin Roper, 35, is charged with vehicular homicide and assault by auto in the Saturday morning crash on the New Jersey Turnpike.

The wreck took place about 1 a.m. Saturday when the limo van Morgan was in was hit by a tractor-trailer on the New Jersey Turnpike, police said.

The collision killed Morgan's fellow passenger, comedian James McNair - who performed under the name Jimmy Mack.

Comedians Ardie Fuqua and Harris Stanton were among the injured, as was a man named Jeffrey Millea.

Morgan's publicist said he's showing signs of improvement.

"He has been more responsive, which is an incredibly encouraging sign," publicist Lewis Kay said Sunday.

A young, beloved teacher found killed in the woods. A 14-year-old student in custody, charged with her murder.

That much we know. But hours after both were found - one dead, one alive - in suburbs northeast of Boston, much remains unknown as to why Colleen Ritzer was brutally slain.

"It's just surreal how quickly someone can go, and how much we take for granted everyday," said Danvers High School student Chris Weimert, describing Ritzer as "the nicest teacher you could ever have. ... I can't believe it."

Authorities had been looking for the student, Philip Chism, first, after he was reported missing - with police sending out messages via Twitter and Facebook on Tuesday evening, noting he'd been last seen around 6:30 p.m. and asking for the public's help in finding him.

“Also, the prosecutor's office has indicated that it wants to try Chism as an adult,” reports CNN’s Pamela Brown. But at this point that decision will be up to the grand jury.”

The school is meanwhile remembering Ritzer as a teacher who loved her students and also inspired them to appreciate math. Nicole White and Riley Doyle say they’ll remember Ms. Ritzer’s smile and positivity. (SEE VIDEO BELOW)

White says the school is taking her loss very hard.

“We all got together last night and everybody was really touched by what everyone did,” White says.

“And we were all wearing pink last night because it's her favorite color. And we lit the candles and everything and it's just been hard for everybody, but coming together last night I think made things a lot better.”

“I think a lot of people were shocked and were really turning to each other for a lot of support because we're all feeling the same way,” Doyle says. “So it's been nice to really have classmates who are there for you.

Franklin Country coroner Paula Gorniak's statement Thursday night disputed allegations from Ohio corrections officials that the man who kidnapped, held captive and raped three girls for nearly 10 years, died accidentally in his jail cell.

Castro was found in his cell dangling from a bed sheet with his pants and underwear down, corrections officials said. But that's not enough evidence to back up the notion, Gorniak said. His pants may have slipped off while he was hanging, she said.

Gorniak said she was not made aware that Castro was found with his pants down in the jail cell, but that does not change the cause of death.

There were no signs that he was sexually stimulated, she said.

"I did the autopsy myself. I saw the ligature. I saw the pictures of the cell. It was a suicide."

“During his month in state prison, officials say Castro was given more than one mental health evaluation and ‘indicated no current suicidal thoughts or past attempts to hurt himself.’ As a result, he was not placed on suicide watch,” reports CNN’s Pamela Brown.

“And the probe also found two prison guards allegedly failed to routinely check on Castro at staggered 30 minute intervals like they were supposed to and even created false logs to make it look like they did, including five false entries the day Castro died. They have been placed on administrative leave while authorities investigate.”
